Buy hydraulic cartridge check valve samples 3 times a year, and hit AAK with a big order for the fou

1 year ago, Ferdinand from Germany left a message on AAK Hydraulic Valve website: Is there a hydraulic cartridge check valve equivalent to HydraForce? Ferdinan bought two hydraulic cartridge check valve samples from the model number I provided, then there was no news. Three months later, he bought another two samples of hydraulic cartridge check valves equivalent to SUN. Six months later, he sent a customized hydraulic cartridge check valve drawing and brought 6 samples, there was no email for 6 months. I think it's a bit abnormal, but if something is abnormal, there must be evil. He bought hydraulic cartridge check valve samples from AAK 3 times a year to test my patience and inspect the manufacturing quality of AAK. I can only comfort myself in this way.

Last month, Ferdinand sent an email asking about the lead time for 1,200 pcs of hydraulic cartridge check valve customized last time.
